There's so much we don't know about this imaginary world that I don't think this is a fair assessment. If, early on in the evolution of animals with brains, it was typical for them to communicate through these connections, wouldn't it make sense for all descendant animals to also have this ability? If contact between divergent species was still frequent, and the contact was positive and mutually beneficial, why not communicate through this channel when needed? Spoken language may have been unique to their humanoids. Indeed, spoken language is a bit more odd than directly connecting to the brain of the other. To me, this is just as unusual or counter to evolution as our ability to use sign language to communicate (albeit primitively) with apes, or give spoken orders to dogs. That is: it isn't.
